ELL-6RH151M Equivalent & Substitute Parts

Part Overview

The ELL-6RH151M is a 150 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 250 mA with 1.8Ohm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part is surface-mounted in a nonstandard package measuring 6.40mm × 6.00mm with a maximum seated height of 2.80mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELL-6RH151M is determined by the following critical parameters:

• Inductance Value: 150 µH (fixed requirement)
• Current Rating: Minimum 250 mA (substitute must meet or exceed)
• DC Resistance: Maximum 1.8Ohm (substitute must not exceed)
• Shielding: Shielded construction required
• Mounting: Surface mount, nonstandard package
• Inductance Test Frequency: 100 kHz
• Compliance: ROHS3 compliant, MSL 1

Two active substitute parts meet these electrical and mechanical criteria: B82462G4154M000 (EPCOS - TDK Electronics) and SRR5028-151Y (Bourns Inc.). Both maintain the 150 µH inductance specification, exceed the 250 mA current requirement, and provide shielded construction with superior DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with ROHS3 compliance and MSL 1 ratings, providing procurement continuity for the obsolete ELL-6RH151M.

B82462G4154M000 offers the lowest DC resistance at 1.05Ohm maximum and the highest current rating at 380 mA. It includes AEC-Q200 automotive qualification and operates across an extended temperature range of -55°C to 150°C. Physical dimensions are 6.30mm × 6.30mm with 3.00mm maximum seated height, representing a minimal footprint change from the original part.

SRR5028-151Y provides the lowest DC resistance at 900mOhm maximum and a smaller footprint at 5.80mm × 5.80mm. It delivers a current rating of 330 mA and operates from -40°C to 125°C. This part includes specified Q factor (7 @ 796kHz) and self-resonant frequency (7.5MHz) data.

Selection between these substitutes depends on thermal requirements, available PCB space, and temperature operating range specifications for the application.

Frequently Asked Questions (FAQ)

Q: Can B82462G4154M000 or SRR5028-151Y be used as direct replacements for ELL-6RH151M?

A: Both parts meet the core electrical requirements: 150 µH inductance, shielded construction, surface mount configuration, and current ratings exceeding 250 mA. Physical dimensions differ slightly; verify PCB layout compatibility before implementation.

Q: What is the primary difference in DC resistance between the three parts?

A: The ELL-6RH151M specifies 1.8Ohm DCR. B82462G4154M000 provides 1.05Ohm maximum, and SRR5028-151Y provides 900mOhm maximum. Lower DCR values reduce power dissipation and heat generation in the inductor.

Q: Are there temperature operating range considerations?

A: The original ELL-6RH151M does not specify operating temperature limits. B82462G4154M000 operates from -55°C to 150°C, while SRR5028-151Y operates from -40°C to 125°C. Select based on application thermal requirements.

Q: Do the substitute parts fit the same PCB footprint?

A: No. The ELL-6RH151M measures 6.40mm × 6.00mm × 2.80mm. B82462G4154M000 measures 6.30mm × 6.30mm × 3.00mm, and SRR5028-151Y measures 5.80mm × 5.80mm × 3.00mm. Verify PCB layout clearances and height constraints before substitution.

Q: What compliance certifications apply to the substitute parts?

A: Both B82462G4154M000 and SRR5028-151Y are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). B82462G4154M000 additionally carries AEC-Q200 automotive qualification.

Q: How do inductance tolerances compare?

A: ELL-6RH151M and B82462G4154M000 both specify ±20% tolerance. SRR5028-151Y specifies ±30% tolerance, representing a wider acceptable inductance range.
